6. Insulate pots and nutrient tanks

Radiant heat from your grow light warms up nutrient tanks, black plastic pots and the nutrient solution in them. This undoes some of your chiller’s work!

To make sure this doesn’t happen, insulate your nutrient tank and pots (especially Oxypots). A lot of growers use reflective sheeting. Since you'll need to move it about to access your pots and tank, make sure you use really durable sheeting. We recommend using Total Blackout Sheeting - it's really robust (3 layers thick).

7. Don’t just cool the water in your brain

A lot of people using a RUSH or R-DWC system simply chill the water in the brain unit, which is then circulated round their system.

It’s fine to do this way - most people do.

However, you may end up cooling water that’s already cold. A more efficient way is to pump warm nutrient solution into your chiller from one end of your system, then pump chilled nutrient solution back out to the other end of your system.

Doing it this way makes your chiller far more effective at cooling the whole nutrient capacity in your system. It also helps keep the temperature around your system more constant and balanced.

For other systems (Gro-Tanks, Multi-Ducts or other systems with tanks), you can simply chill the nutrient in your reservoir.

Grow rooms can smell pretty funky! You don’t want any tell-tale odours escaping your tent or home. Odour control is key. To get their aroma, plants release volatile organic compounds (VOCs) into the air. The good news is these can be removed. Here are 6 things you should do.
